That's what the SHIELD tv series is for lol. So that we can have a whole cast of characters who can easily be killed off (especially since they are Whedon creations) instead of using people like Coulson or any other actual Marvel SHIELD character. Expect the likes of Melinda May or Agent Skye to bite the dust at some point.

That's more or less a Joey Q. thing. He IS still part of the Creation team for the films, even tho he's no longer editor at the Comics
